Classify the lines: -3x + y = -1 -6x + 2y = 8 a) parallel b) perpendicular c) neither parallel or perpendicular d) skew

A) Parallel

Step-by-step explanation:

So let’s put them into y intercept form. So y=3x-1 and 2y=6x+8 or y=3x+4. Since they both have the same slope, they are parallel.

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
